Discharge pump

Abstract

Description

[Technical Field]

[0001] The present invention relates to a discharge pump. [Background technology]

[0002] A bottle with a discharge pump is used to draw up and discharge a predetermined amount of liquid content from the bottle by depressing the pump head (for example, Patent Document 1). Cosmetics, shampoo, conditioner, etc. are contained in the bottle with a discharge pump, and it has been common practice to distinguish the product by coloring the discharge pump according to variations in the scent, etc., of the liquid content. However, the specific scent of the liquid contents, as well as other properties such as color and feel, cannot be confirmed without removing the discharge pump from the bottle. Therefore, in order to allow customers to check the scent, color, feel, and other properties before purchasing the product, a sample of the liquid contents in the bottle had to be prepared as a separate item.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-6418 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made in view of the above-mentioned conventional situation, and has as its object to provide a discharge pump that does not require the addition of a sample of the liquid contained in the bottle. [Means for solving the problem]

[0005] As a result of extensive research into solving the above problems, the inventor discovered that if a sample storage chamber capable of storing a sample of the liquid contained in the bottle is formed in the head portion of the discharge pump, it would be possible to eliminate the need for a separate item for the liquid contained in the bottle, and thus completed the present invention.

[0006] That is, the present invention solves the above-mentioned problems by providing a discharge pump characterized in that a sample storage chamber having an opening with an openable lid is formed in the head portion of the discharge pump. [Effects of the Invention]

[0007] With the discharge pump of this invention, by opening the lid of the sample storage chamber in the head, it is possible to check the scent of the liquid in the bottle, as well as other properties such as color, feel, etc. This eliminates the need to prepare a separate sample of the liquid in the bottle, thereby reducing the cost and effort required to prepare such a sample.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] First, a first embodiment of the present invention will be described with reference to FIG. In Fig. 1, reference numeral 10 denotes a discharge pump, and its head 11 is formed with a sample storage chamber 13 having an opening 12 with a one-sided double-door type opening / closing lid 14. Discharge pump 10 is connected to a tube (not shown) via stem 15 and attached to a bottle.

[0011] A sample P of the liquid contained in the bottle is stored in the sample storage chamber 13. Examples of the liquid contained in the bottle include liquid hair care products such as shampoo and conditioner, liquid soaps such as body soap and hand soap, cleaning agents such as kitchen detergents, and household products such as deodorizers, disinfectants, and insect repellents. The form of the sample P is not limited to the same form as the liquid contained in the bottle if the only purpose is the "fragrance," and it can be in a solid, semi-solid, liquid, or other form as long as it produces the same fragrance. If it is a liquid, it can be a two-liquid separation type or a reactive type that produces fragrance when mixed, but solid forms such as tablets or beads as shown in Figure 1 are preferable because they are easy to handle. If the objective is to achieve properties other than "fragrance," such as color and feel, the liquid should be in the same form as the liquid in the bottle.

[0012] The means for forming the sample storage chamber 13 is not particularly limited, but it is simple to form it by providing an appropriate recess in the head portion 11.

[0013] In this first embodiment, the one-sided hinged opening / closing lid 14 is roughly triangular in shape, with one side of the lid (the pump outlet side) attached to the head part 11 by a leg shaft 14a attached to the bottom, and the other side being able to be opened and closed freely up and down. As shown in Figures 1(d) and (e), by opening the single-sided double-door opening / closing lid 14 upward, the sample P stored in the sample storage chamber 13 is exposed and exposed to the outside air, allowing the scent of the liquid in the bottle to be confirmed by the scent of the sample P. Furthermore, if the sample P has the same form as the liquid in the bottle, the properties of the liquid in the bottle, such as color and feel, can also be confirmed. After confirmation, as shown in Figures 1(b) and (c), the lid can be closed downward to block the outside air, preventing the scent from evaporating.

[0014] Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 2, reference numeral 20 denotes a discharge pump, and a sample storage chamber 23 having an opening 22 with a substantially circular rotary open / close lid 24 is formed in a head portion 21 thereof. The rotary opening / closing lid 24 has an inner lid portion 24a having a pair of openings 22 which is fitted over the sample storage chamber 23, and an outer lid portion 24b which has an opening 22a corresponding to the openings 22 and a pair of guide protrusions 24c at the bottom which is fitted over the head portion 21 including the inner lid portion 24a so as to be rotatable along a pair of guide grooves 21a formed in the head portion 21. 2(d) and (e), when the rotary opening / closing lid 24 rotates the outer lid portion 24b, the opening 22 of the inner lid portion 24a and the opening 22a of the outer lid portion 24b are connected, and the sample P stored in the sample storage chamber 23 is exposed to the outside air, allowing the aroma of the liquid contained in the bottle to be confirmed by the aroma of the sample P. After confirmation, as shown in FIGS. 2(b) and (c), the outer lid portion 24b can be rotated in the opposite direction to shift the positions of the opening 22 of the inner lid portion 24a and the opening 22a of the outer lid portion 24b, thereby disengaging them from each other, thereby closing the openings and preventing the evaporation of the aroma. In this embodiment, the aroma of the liquid contained in the bottle can be confirmed mainly by the aroma of the sample P.

[0015] Next, a third embodiment of the present invention will be described with reference to FIG. In FIG. 3, reference numeral 30 denotes a discharge pump, and a sample storage chamber 33 having an opening 32 with a sliding open / close lid 34 is formed in a head portion 31 thereof. The sliding open / close lid 34 has a pair of guide protrusions 34 a on the bottom, and is attached to the head part 31 so as to be slidable along a pair of guide grooves 31 a formed in the head part 31 . As shown in Figures 3(d) and (e), sliding the sliding opening / closing lid 34 in the direction opposite the discharge side of the pump opens the opening 32, exposing the sample P stored in the sample storage chamber 33 and allowing it to communicate with the outside air, allowing the aroma of the liquid in the bottle to be confirmed by the scent of the sample P. Furthermore, if the sample P has the same form as the liquid in the bottle, the properties of the liquid in the bottle, such as its color and feel, can also be confirmed. After confirmation, as shown in Figures 3(b) and (c), sliding the lid toward the discharge side of the pump closes the opening 32, blocking off access to the outside air and preventing the evaporation of the scent.
